' To at! rui/rom 'it may concern:

De it known that we, VICTOR GELPKE, a citizen of the Republic of Switzerland, and resident of Lucerne, Switzerland, and PAUL KUGEL, a subject of the Emperor ot Germany, and resident of Dusseldorf, Germany, j have mventedcertam new and useful Im-f illustrating the new valve in a .complete re ul-ating device, Fig. 2 is a central longitu inal section through our hydraulic regulator valve on a larger scale, Fig. 3 is" a transverse section through a detail of' Fig. Q, Fig. l is a view, similar to Fig. 1, illustrating a modification of lour hydraulic regulator valve.

Similar letters refer to similar parts throughout the several views:

It is to be understood that. there isavailable a motive fluid which is lcd by the governor to the one or the other side of a piston, movingwith its rod the device which allows the working fluid to enter the turbine or the like.

E in Fig. 1 is a cylinder which contains the aforesaid piston designated by the letter Gr and connected to the piston -rod H, which projects through suitable stuflin g boxes in opposite ends of the cylinder, being connected at the upper end to the above mentioned dcvice, determining the admission of the water, gas, steam and -the like to the turbine, water wheel and the like. This device is not'shown in thepresent drawing as it.` forms no part of our invention.

M represents a stationary valve casing which has an inlet port C for the motive fluid, an outlet port R and branch ports D and F which are designed to be connected to the ports D1 and F1 at opposite ends ot the cylinder E by rigid pipes not shown. The flow Of the motive fluid for operating the/regulating piston is controlled by the valve B, which is arranged in the valve casing M. Between the valve B and the stationary casing M we provide a movable part Z) which is in the shape of a cylinder` having ports corresponding respectively to the ports of the casing of which ports g designates the inlet port of the motive fluid, L and f the ports by which the fluid passes respectively through D or F into the one or the other end ot the regulating cylinder E according to the position of the valve B, c' and Z the ports by which the water escapes from the regulating cylinder. The movement of the part Z2 is eltected by having its lower end con-- nected by a link-L with one end of a rocking lever'K pivoted up'on a fixed pivot I having its other end connected with the lower end of the piston rod H.

The valve B has a central passage .through which passes a spindle al which has a certain amount ofl longitudinal movement in the passage. The upper end of the spindle is connected with the governor A. The space within the movable part of the valve 4casing and surrounding the lower end of the valve, which is designated by the letter Z, is in constant communication through a port u with the space g, which as before stated is in communication with the' mot-ive fluid. This space Z is in communication through a port 0 with a passage through the body of the Avalve B which is `formed by reducing the rod al so as to provide an annular space as shown and lower andupper shoulders c2 and c3. The space Z is only in communication however with this 'annular space when the rod c1 has been moved downwardly by the governor, but when it has been thus moved` downwardly the motive Huid will pass from the space g through the port n into the chamber Z and thence through port 0 and along the rod al and outthrou'gh the port p into the space m above the valve. As the head of the valve isot greater diameter than the lower end, the result will be that the greater pressure on the valve head in the chamber m will move the valve downwardly and this relative movement will cause the shoulders c2 and a3 to close the passage through the valve. v,After this is done the ygovernor has ceased to influence the valve.

manner the fluid `in fm, has lost its pressure the pressure of the fluid-in Z lifts the valve B, closes the shoulder a2 against the bore in the valve B so that the neutral position of the latter against the rod al, shown in Fig. 4, is taken again. Thus arrived the valve B has changed its position against the movable casing part b accordingly to the downward movement of the rod al, consequently it has olpened the ports f and h thereby connecting t em respectively with the spaces g and 1l. The motive fluid now flows from space g through the ports f, F and F1 into the space O below the regulating piston G lifting the latter, while the fluid above the piston escapes through the ports D1, D, L and z' in the outlet R; As soon as the piston Gr moves upwardly the movable part b of the valve casing is moved downwardly by the lever K and link L causing the part b to follow the valve B and to cut off the 'supply 'of the regulatin fluid Ito the cylinder E.

Fig. 4 lllustrates a modified arrangement in which a differential piston is used instead of the piston G, shown in Fig. l, and having working surfaces of the sameA size. To the smaller face of the differential piston the motive fluid is led directly therefore operating with constant pressure, whereas on the upper side of the piston the pressure of the, fluid is working, which is controlled through the governor by means of the valve B. In this arrangement the port f is needless.

Having thus described ourinvention, what we claim is l. In hydraulic regulating apparatus, a hydraulicdistributing valve, comprising a l fixed ported casing, a hollow outer cylindrical valve member slidable in said casing and moved by an auxiliary reciprocating motor regulating a .hydraulic motor, an inner cylindrical valve member slidable in said outer valve member, a central spindle extending axially ofl said inner valve inember, and moved by a governor, substantially as described.

2.*n hydraulic regulating apparatus, a hydraulic distributing valve comprising al fixed ported casing, a hollow outer cylindrical ported valve member slidable in said casing, au inn'er cylindrical Valve member slid'able in said outer valve member having ends Aof unequal cross sectional area, a cen-l tral spindle extending axially of said inner valve member, chamber in one endof said outer valve member permanently connected to the inlet of the casing, a chamber '1n-the opposite end of said outer valve member, ports in said inner valve member forconnecting the chambers in said outer valve member together, this connection being allowed or interrupted by shoulders of the said central spindle, means connectingsaid outer valve to the piston of a reciprocating auxiliary motor, and means connecting said valve spindle to a governor, whereby said valve spindle is operated by said governor to control said ports connecting sald'charnber together, substantially as described.
